Abstract

This paper presents a dynamic voltage restorer (DVR) providing un-interrupted power supply to the load when distributed generation (DG) is integrated to DVR. When there is an outage in supply to the load from the source, the DG integrated DVR supplies the load providing un-interrupted power supply. Photo-voltaic system is considered to be DG and the low voltage output from PV system is boosted using a high-gain DC-DC converter. DVR is a custom power device used for the compensation of power quality issues. DVR compensates harmonics, sag and swell in load voltage in this paper, also providing uninterrupted power supply to the load when there is an outage in supply to the load from the source. Closed-loop operation of high-gain DC-DC converter for boosting DG output is described. The proposed system is simulated and results are obtained using MATLAB/SIMULINK software.
